Abstract
A method of enhancing oxidation of air contaminants on an ultra-low density, UV light accessible aerogel photocatalyst is provided. The method includes the steps of providing a photocatalytic reactor system broadly comprising a photocatalytic reactor cell, a UV light source, and a pump to force the contaminated air stream through the photocatalytic reactor cell. The photocatalytic reactor cell includes glass cell. A catalyst bed formed of a titanium dioxide aerogel is provided in the glass cell whereby a high fraction of the titanium dioxide aerogel is accessible to UV light and gas. The catalyst bed is exposed to UV light from the UV light source and a contaminated air stream is introduced into the photocatalytic reactor cell such that the air stream passes through the catalyst bed causing oxidation of the contaminants of the air stream.
